TopeakRoad Morph G Bike Pump with Gauge, Black/Silver, 3.8” x 2.2” x 1.1”, TRP-3G

So after much deliberation and about 2-3 months worth of use/testing I can say in my opinion that I believe the morph G is pretty good. I have a hybrid bike that I average about 70-80 miles on a week. I find that especially when the weather is hot, my tires don't stay as inflated as when its cold (yay thermo dynamics and air being smaller then the holes in the rubber....) Therefore I've been using the pump quite often with the weather being so hot. I pump my tires to about approximately 70psi using the built in gauge. When comparing it to my other bike gauge, it seems fairly accurate on the 0.0 +/- 2-4 psi. I wouldn't rely on the gauge however if you are trying to be "exact" with your tire pressure. More than likely I would suggest using a nicely calibrated gauge to be precise.Onto the other features!:The foot pedal, is a really nice addition, and makes the process of pumping up the tires much much easier. Previously I had a hand pump without the pedal, and you have to hold both ends....so much WORK. The fold down handle is a nice bonus, (since I was coming from a non-folding hand pump with no food pedal) and it helps to get that force you need to pump up the tire (by being able to use gravity on a larger surface area). Lastly, the Size of this pump isn't small, which can be good or bad depending on what you're looking for. There are smaller versions of this pump, but I chose this pump for leverage, and for ease of pumping up tires. Included in this set up, are reusable zip ties, although I prefer to use Velcro ties on my bike to prevent any kind of paint scratches.Use:I've used it on my bike now fairly often, and its quite easy and effortless to get to 70-80 psi (5-5.5 bar). However, trying to pump up a road bike up in the 100's starts to get pretty rough. If you have a road bike and require almost 2x the psi my hybrid uses, then I would recommend using this pump for "emergencies only." You can do it, and in an emergency, it would be pretty reasonable to get it pumped up quickly, but using it as your main pump/daily pump may be a bit tiring. I would recommend a big floor pump you keep at home for that use. 2nd, this pump is fairly big, and because of that, mounting it can be a bit of a challenge. I recommend taking the measurements and figuring out where you're going to put it on the bike BEFORE purchasing it. I had a hard time myself trying to fit this pump, two water bottles, and a bike chain all the bike when I would go out for a 50 mile ride. So just something to consider.SO! all in all, A great pump, that works very well. Gauge only reads to the 10psi but its alright if you aren't being picky, and can be difficult to pump on higher psi tires, but works very well, and feels very solidly built.

I bought this pump specifically for 3 of its features and it has lived up to my expectations. 1) The pump handle and foot unfold to allow me to stabilize the pump with my foot while it rests on the ground. It’s so much easier to pump than a handheld pump. 2) The built in gauge shows you the pressure while you’re pumping- a real time saver and convenience. 3) It takes seconds to convert the pump nozzle from presta to shrader and back which has been terrific for helping fellow riders. The available built-in mounting options were terrific. The pump has remained secure and in place while riding. I love this pump!

I've had this product for 5 months now, and after using it on a weekly basis, I feel I can give an informed review.As far as looks and feel, the pump feels fairly light in my hand but solid and well-built at the same time. The machined barrel is very smooth with no rough spots. I think the metal barrel is made from aluminum. The pump is fairly sleek looking when mounted on my bike, so no complaints there.The really cool feature of this pump is that several portions of the pump are movable (morph-able), making it more convenient for emergency pumping on-the-go. The handle, which is held in place by turning the handle until it clicks into the barrel, snaps outwards (pivots) 90 degrees, allowing the user to use his/her body weight to pump when the pump is held against the floor. This is advantageous because it allows more force to be generated, less arm strength be used, and less energy be expended by the user when pumping tires. The foot pedal, as I call it, snaps outward (pivots) 90 degrees from the base, allowing the user to hold the pump in place using his/her foot while pumping. After unhooking the head of the hose from the hook, the head can actually be pulled out, exposing about ~3 inches more of rubber hose, allowing the user better reach the valves on the tires. The pump head adapters can also fit both shrader and presta valves by flipping the two rubber/plastic adapters.To pump your tires, fit the head over the valve, pull the lever out to lock it in place (so it forms a "T" shape), and commence pumping. When I pump my road bike tires (Continental Gatorskins 28x700C) up to 100 psi, it takes a considerable amount of effort, but much less than other hand pumps that I've used. When I reach about 80 psi, I really have to use my body weight as leverage to pump it up to 100 psi(about 25 pumps more). Additionally, the pressure gauge works pretty well. After pumping, the base of the aluminum will get fairly warm, thanks to the gas relation, Gay-Lussac's Law. It doesn't get hot by any means, but it will get pretty warm. It should be noted that the pump only pumps air when you compress the pump, i.e. the pump does not pump air when you pull and push -- only when you push. My previous "Topeak Mini G MasterBlaster Bike Pump with Gauge" pumped both ways, but it required more effort to use.As far as mounting goes, you can either secure the bracket to your bike using large zip ties (provided) while putting the included rubber pieces between the bracket and bike frame to prevent movement, or you can secure it to your bike using the included screws. At first I tried using the zip ties, but after tightening the ties and trimming the plastic down, the sharp corners of the trimmed zip ties were scratching my legs/clothing so I switched to the screws (replaced my water bottle cage with the mounting bracket).There is a little bit of play (wiggles around) when the hose head is snugly underneath the hook. Sometimes I fear that the hose will pop out and accidentally get caught in my chain (It's mounted to my down tube.), but it hasn't happened -- yet. When mounting to your bike, I would snap the pump into the mounting bracket and pull the velcro over *both* the barrel and the rubber hose to hold both in place.What I really like about this pump is that this pump is pretty much like a miniature floor pump. The rubber hose ensures flexibility while pumping so the user does not accidentally tear a hole around the tire's valve from too much strain; this is very important and is a common problem with mini pumps without hoses. I also like the gauge, which is pretty accurate, at least when I use my "Planet Bike 1002-3 ALX Floor Pump with Love Handle" to check the pressure anyway. What I don't like is how the foot pedal takes a considerable amount of effort to open (unsnap). Don't use your nail, for you might accidentally injure yourself when prying it open. Use the tips of your thumb and middle finger, and squeeze along the sides until it comes apart; this is the best method for me, at least.Overall, this is a terrific pump for when you don't have access to a full-sized floor pump. It certainly feels solid and is much better than the other mini pumps out there that don't have flexible hoses, but it's not meant to replace a floor pump by any means! It only takes me about 5 pumps to reach 100 psi from 80 psi using my dedicated floor pump and nearly 5 times as many pumps to do the same using this pump.

excelente producto, muy práctico y ligero!

Die Luftpumpe funktioniert bestens. Egal ob Dunlop, Autoreifen oder französische Ventile lassen sich damit universell aufpumpen.Dadurch muss nur der Stutzen am Ende gedreht werden. Dies wird in der Anleitung entsprechend beschrieben.Die Verarbeitung ist sehr gut und wirkt so, als wenn man lange Freude daran haben wird.

Picked up this pump for my road bike because I was looking for something portable and easy to use.It's lightweight and can be easily attached to your bike so you can always have it with you whenever you're out riding.It's easy to attach the pump to Schrader valves and the small bracket keeps a tight connection between the pump and tire tube.The foldout footpad helps keep the pump stable when you're using it just like using one of the bigger ones.This is a great bicycle pump for using on your bike in case you get a flat and for topping your tires off at home before heading out for a ride.The only drawback is that it gets hard to pump over pressures of 100PSI, otherwise it's perfect.

Large yet helps to pump air with less effort which is imporant for me on the road. Good choice.

Loved this. Threw out the old pump. This works well for all tube types. Nice solid pumping action. Tube section expands by lengthening. Hand foot pedal fold out to stabilise base.Great fixing to the framework
